STOVE Specification of Letters Patent.

Patented Feb. 4, 1908.

Application filed August 23. 1907. Serial No. 389321- T all whom it may concern:

Be it known that I, ERNEST C. COLE, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented an Improvement in Stoves, of which the following is a specification.

This invention is an improvement in draft devices for use in stoves, and consists in certain novel constructions and combinations of parts as will be hereinafter described and claimed.

vided with my improvements.

In the drawing, Figure 1 is a perspective view' of the upper portion of a stove pro- Fig. 2 is a vertical longitudinal section of a part thereof. Fig. 3 is an elevation from the inner side of the stove showing the doublecup shape draft flue and a portion of the stove casing. Fig. 4 is a detail perspective view of the double cup shape draft flue. Fig. 5 is an elevation of a portion of the stove casing showing the draft inlets and Fig. 6 is a detail view of the valve or damper.

In my inventionI seek to provide a novel form of draft arrangement at the rear side of a stove just below the smoke pipe collar, so

constructed as to provide for throwing the air upward into the smoke pipe and chimney, or downward on to the fire asmay bev desired. In securing this result, I provide the stove casing A with two air-inlets 1 and 2 and an intermediate partition 3 as best shown in Fig. 5, and together therewith provide flue connections C and D, the flue connection C discharging upwardly and the flue connection Ddischarging downwardly, and said connections C and D belng 1n communik cation, respectively, with the draft inlets '1' and 2, so that when the inlet 1 is opened, the draft will be thrown upward into the chimney where it will act as a check-draft, and

when the inlet 2 is opened, the draft will be thrown downward, operating as a slow-burning draft, and both inlets may be closed by the controlling device presently described.

,The flues D and C are preferably integral and form parts of a double cup shape draft flue E, whose flues D and C in the form of cups, open at the same side toward the inner surface of the stove casing A, and have an intermediate partition E alined, when the cup shape flue is applied to the stove casing, with the partition 3 between the inlet openlngs, and said flues D and C open, respectively at their lower and upper ends, and perforated lugs E are provided to facilitate the connection ofthe cup shape draft flue with the casing of the stove.

It will be noticed that the check draft admitted through opening 1 cannot get down into the stove, as its outlet or discharge at its upper end will be above the level of the stove, and the entire air admitted as a check will so operate, and no portion of it can pass down ward into the stove to operate as a burning draft.

The purpose of the down-draft through the flue D 1s to furnish a surface combustion whereby to burn.the gas and prevent the pufling of the stove from the accumulation of gases 1n the up er part thereof.

It is regarde as lmportant to arrange the outlet of the flue C substantially above the highest point of the combustion chamber so that no portion of the check draft can pass into the combustion chamber for the purpose valve F is adjusted to admit air through the inlet '1, whence it may pass up the flue C to operate as check draft. If the valve Fbe now given a third turn to the right, its portion F will close the inlet 1 and open the in-'= let 2, permitting air to enter and go down to produce a surface combustion, and if the damper be now given a further third turnt the right, both inlets 1 and 2 will be" closed, the damper assuming the position shown in' Fig. 6, and the lug f on the damper abutting a stop G on the stove casing, the damper also havin a lug f which will abut the opposite sideof the stop G when the damper is in the position shown in Fig. 1 to admit air through the inlet 11 to theflue C.

I claim; w

1. The combination of a stove casing hav ing a pair of inlet openings, and valve devices controlling the same, of a double cup shape draft flue on the inner wall of the casin 0 on at its side next the said inner wall an o osed at its opposite side and having an up' rvardly opening flue communicating with one of the inlet openings, and a downwardly opening flue communicating with the other inlet opening, substantially as and for the pur- 5 poses set forth.

2. In a stove a draft attachment having fines and open at one side and closed at its 0p osite side, whereby it may fit at its open Sl( e against a stove wall having inlet openings communicating with their respective flues and having a downwardly opening flue closed at its upper end and an upwardly opening flue closed at its lower end, the said flues being uncommunieating and arranged side by side with the lower end of the upwardly opening flue lapping alongside the upper end of the downwardly opening flue.

3. The combination of a stove casing, having a pair of adjacent inlet openings, a damper pivoted between and controlling the said openings, an upwardly opening flue in communication with one of the inlet openin s,

and a downwardly o ening flue alongside tie upwardly opening ue and communicating with the other inletopening, substantially as set forth.

4. The combination in a stove, with the casing and the pipe collar, of a double cup sha e draft flue arranged within the casing, an having an upwardly opening flue discharging at its upper end and extending at such end within the pipe collar, and also pro vided alo side the said upwardly opening flue with ai d ownwardly opening flue discharging to the combustion chamber, the casing havi inlet openings communicating with said ues and a damper having an opening which may be adjusted into register with either of said inlet openings, substantially as 40 set forth.

5. The combination in a stove casing with a pair of inlet 0 enings and a double cup shape draft flue aving an upwardly opening flue communicating with one of the inlet openings, and a downwardly opening flue alongside the upwardly opening flue and communicatin with the other inlet opening, and a damper aving an opening which may be adjusted into register with either of the inlet openi s and also having an imperforate portion which may be adjusted to close either or both of said openings, all substantially as and for the purpose set forth.

6. A stove, having a pair of adjacent inlet openings, and a double cup shape. draft flue having an upwardly opening flue communicating with one of the inlet openings, and a downwardly opening flue communicating with the other opening, and a valve pivote between said inlet 0 enings and controlling the same, substantia y as set forth.

7. A stove casing havin inlet openings, and a partition between t e same, and a double cup shape draft flue havin an upwardly opening flue and a downwar 1y opening flue alongside the said upwardly openingflue, and an intermediate partition between said flues and in line with the partition between the inlet openings, substantially as set forth. A

8. In a draft attachment for stoves, a double cup shape draft flue having a pair of uncommunicating flues arranged side by side and eachclosed at one end and 0 en or discharging at the other end, one 0 said flues discharging at one end of the draft attachment, and the other at the other end thereof, and means controlling the passage of air to said flue substantially as set forth.

9. The combination in a stove casing, with a pair of inlet openings and fines commumcating therewith, of a damper having an imperforate portion which ma be adjusted to close either or both of sai inlet ope s, and also having an opening which may e adjusted into register with either of said inlet openings, substantially as set forth.

10. The combination of a stove casing-havin inlet openings arranged laterally to each other and in close proximity, and a double cup shape draft flue having upwardly and downwardly opening fiues arrarged alongside each other with the upwar y opening flue communicating with one of the inlet openings and the downwardly opening flue communicating with the other inlet opening, and means controlling the said inlet openings, substantially as set forth.
